OT Security Officer
We are seeking an experienced OT Security Officer to help protect operational technology environments that support essential industrial processes. In this role, you will develop, maintain and improve security measures across industrial control systems, supervisory control and data acquisition platforms, manufacturing networks and other operational technology assets. You will work closely with engineering, IT, operations, maintenance and risk teams to ensure that security is embedded into daily operations while maintaining safety, availability and reliability.
Your responsibilities will include identifying and assessing OT security risks, maintaining asset inventories and network diagrams, supporting vulnerability management, reviewing access controls and monitoring security events. You will help establish and maintain policies, standards and procedures aligned with recognised frameworks such as IEC 62443, NIST Cybersecurity Framework and relevant regulatory requirements. You will also contribute to incident response planning, investigations and recovery activities, coordinate security assessments, and support the secure design and commissioning of new systems. Where required, you will assist with audits, supplier reviews, penetration testing and the implementation of corrective actions.
The successful candidate will have practical experience in OT, ICS, SCADA or industrial network security, together with a sound understanding of network architecture, segmentation, firewalls, remote access, identity management and security monitoring. Experience working in safety-critical or regulated environments is highly desirable. Relevant professional qualifications, such as GICSP, CISSP, CISM, IEC 62443 certification or equivalent, would be advantageous. You should be analytical, methodical and confident communicating with both technical and non-technical stakeholders. The role requires the ability to manage competing priorities, influence good security practices and work collaboratively in environments where operational continuity is essential.
